26 Ninoe Kinberg, 1865 Characteristics. Prostomium conical, with a pair of dorsal slit-like organs. Parapodia uniramous, with simple limbate chaetae and simple multidentate hooded hooks. Anterior parapodia with a number of digitiform postchaetal branchial lobes. Mx IV or mx III and IV with denticulate incisive edges. Taxonomy: The genus is characterised by the branched branchial lobes in the anterior part of the body and the dentition of mx III and IV. The genus is represented by a number of species in warm waters. One species is known from the area. Branchiae from chaetiger 5-6 to 31-39, up to five filaments from chaetiger 20, simple hooded hooks from chaetiger 7-15, mx III bidentate, mx IV with 7-8 fine teeth ……........………… ............................................................................................ Ninoe armoricana Glemarec, 1968 Length 30-40 mm, width 1.5 mm N Atlantic, Bay of Biscay, moderate depth Figs from left: anterior end; parapodium 24, anterior view; maxillae. From Glémarec (1968).
Scoletoma Blainville, 1828 Lumbrineridae from NE Atlantic waters Characteristics. Prostomium conical or globular, occasionally with a single occipital antenna. Parapodia uniramous, with simple limbate chaetae and simple multidentate hooded hooks. Aciculae yellow or black. Mx III unidentate or bidentate. Mx V free-standing, placed outside of mx IV. Taxonomy: Frame (1992) resurrected Scoletoma as a valid genus to encompass species with simple hooded hooks and simple limbate chaetae, which previously had been referred to Lumbrineris. As currently defined, Scoletoma and Lumbrineris are rather close, and are essentially distinguished only by the lack and presence of composite hooded hooks, respectively (Frame 1992, Carrera-Parra 2006a). Scoletoma impatiens (Claparède) has been synonymised with Lumbrineris tetraura (Schmarda) by various authors. Winsnes (1980) and Orensanz (1990), however, have clearly indicated that the two species are different. Scoletoma funchalensis (Kinberg) is poorly known and possibly confused. Note: Juvenile specimens of Lumbrineris and Hilbigneris may lack composite hooded hooks and key out as Scoletoma. 1.

Scoletoma impatiens (Claparède, 1868) 27 [=Lumbrineris tetraura: Hartmann-Schröder 1996, non Schmarda, 1861] Length > 100 mm, width 3-5 mm North Atlantic, widely distributed Figs from left: anterior end; parapodium 18; posterior hooded hook; maxillae. From Hartmann- Schröder (1996) (as L. tetraura).
